Produção brasileira em periódicos psiquiátricos de alto fator de impacto em 2005

OBJETIVO: Avaliar a produção científica brasileira, no ano de 2005, nas 20 revistas de psiquiatria com maior fator de impacto (FI) segundo o Journal of Citation Report (JCR), 2004. MÉTODOS: Do total de 90 periódicos com FI variando de 11,207 até 0,13, selecionamos todos os artigos dos periódicos com FI acima do percentil 75 (n = 20). Avaliamos, entre esses artigos, quantos apresentavam pelo menos um autor brasileiro, quantos eram compostos por equipe exclusivamente brasileira ou tinham pelo menos o primeiro autor e/ou o autor sênior filiado à instituição nacional. Avaliamos também a respectiva distribuição das publicações por estados de acordo com a instituição de filiação do(s) autor(es). RESULTADOS: Entre 4.859 artigos avaliados, 54 (1,11%) tinham pelo menos um autor com afiliação a instituição brasileira e 22 tinham autor sênior brasileiro, excluindo-se as 32 publicações compostas exclusivamente por pesquisadores brasileiros. Ao se determinar a distribuição, por estados, da instituição de pesquisa à qual está(ão) vinculado(s) o(s) autor(res) brasileiro(s), São Paulo, com 34 publicações (55,73%), ficou na primeira posição, com predominância absoluta do eixo Sudeste-Sul (96,72%). CONCLUSÃO: Apesar de as publicações brasileiras em psiquiatria terem apresentado aparente crescimento quantitativo e qualitativo, a produção científica da área é ainda pequena e altamente concentrada em alguns poucos estados.

Prevalência de suicídio no Sul do Brasil, 2001-2005

OBJETIVO: Descrever e avaliar a incidência de suicídio em indivíduos procedentes da Associação dos Municípios da Região de Laguna (Amurel), no período de 2001 a 2005. MÉTODOS: Estudo transversal com coleta de dados no Instituto Médico Legal (IML) de Tubarão, referentes a todos os óbitos ocorridos entre 2001 e 2005, que tiveram como causa de morte o suicídio. Para todos os casos inclusos no estudo, os dados foram retirados dos prontuários do IML por meio do preenchimento de uma ficha de dados. RESULTADOS: A idade média dos suicidas pesquisados ficou em 44 anos, com predomínio do sexo masculino (79,6%). A maioria dos casos não tinha união estável (38,8%) e utilizou com mais freqüência o enforcamento como método, com 68,4% dos óbitos. As profissões mais comuns entre os suicidas foram os serviços gerais e agricultores. A cidade com mais incidência foi Grão Pará com coeficiente de 20,2. CONCLUSÃO: Verificou-se que a incidência da região de Amurel está dentro das estatísticas catarinenses com coeficiente de 7,9. O principal método para cometer o suicídio foi o enforcamento, e os homens se matam quase quatro vezes mais que as mulheres.

Critical analyses of the introduction of liquid-based cytology in a public health service of the state of São Paulo, Brazil

OBJECTIVE The aim of this study was to compare the performance of the current conventional Pap smear with liquid-based cytology (LBC) preparations. STUDY DESIGN Women routinely undergoing their cytopathological and histopathological examinations at Fundação Oncocentro de São Paulo (FOSP) were recruited for LBC. Conventional smears were analyzed from women from other areas of the State of São Paulo with similar sociodemographic characteristics. RESULTS A total of 218,594 cases were analyzed, consisting of 206,999 conventional smears and 11,595 LBC. Among the conventional smears, 3.0% were of unsatisfactory preparation; conversely, unsatisfactory LBC preparations accounted for 0.3%. The ASC-H (atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion) frequency did not demonstrate any differences between the two methods. In contrast, the incidence of ASC-US (atypical squamous cells of undetermined significance) was almost twice as frequent between LBC and conventional smears, at 2.9 versus 1.6%, respectively. An equal percentage of high-grade squamous intraepithelial lesions were observed for the two methods, but not for low-grade squamous intraepithelial lesions, which were more significantly observed in LBC preparations than in conventional smears (2.2 vs. 0.7%). The index of positivity was importantly enhanced from 3.0% (conventional smears) to 5.7% (LBC). CONCLUSIONS LBC performed better than conventional smears, and we are truly confident that LBC can improve public health strategies aimed at reducing cervical lesions through prevention programs.

A busca da comunicação na sociedade multi-ecrãs: perspectiva ecológica

Este texto reflexiona sobre una nueva forma de concebir la televisión como servicio público, resaltando las dificultades y problemas que plantea analizar el concepto de la calidad de la televisión, si no se tiene en cuenta la dimensión emotiva y de entretenimiento del medio. Posteriormente, el autor pretende ubicar la televisión en el contexto de la multiplicidad de otras pantallas y tecnologías, subrayando las cuestiones del sentido y de la calidad de vida, desde un modelo ecológico. Finalmente, se apuntan algunas contribuciones para profundizar el concepto y las experiencias de alfabetización digital.

Concise server-wide causality management for eventually consistent data stores

Large scale distributed data stores rely on optimistic replication to scale and remain highly available in the face of net work partitions. Managing data without coordination results in eventually consistent data stores that allow for concurrent data updates. These systems often use anti-entropy mechanisms (like Merkle Trees) to detect and repair divergent data versions across nodes. However, in practice hash-based data structures are too expensive for large amounts of data and create too many false conflicts. Another aspect of eventual consistency is detecting write conflicts. Logical clocks are often used to track data causality, necessary to detect causally concurrent writes on the same key. However, there is a nonnegligible metadata overhead per key, which also keeps growing with time, proportional with the node churn rate. Another challenge is deleting keys while respecting causality: while the values can be deleted, perkey metadata cannot be permanently removed without coordination. Weintroduceanewcausalitymanagementframeworkforeventuallyconsistentdatastores,thatleveragesnodelogicalclocks(BitmappedVersion Vectors) and a new key logical clock (Dotted Causal Container) to provides advantages on multiple fronts: 1) a new efficient and lightweight anti-entropy mechanism; 2) greatly reduced per-key causality metadata size; 3) accurate key deletes without permanent metadata.

Pervasive adaptive data acquisition gateway for critical healthcare

The data acquisition process in real-time is fundamental to provide appropriate services and improve health professionals decision. In this paper a pervasive adaptive data acquisition architecture of medical devices (e.g. vital signs, ventilators and sensors) is presented. The architecture was deployed in a real context in an Intensive Care Unit. It is providing clinical data in real-time to the INTCare system. The gateway is composed by several agents able to collect a set of patients’ variables (vital signs, ventilation) across the network. The paper shows as example the ventilation acquisition process. The clients are installed in a machine near the patient bed. Then they are connected to the ventilators and the data monitored is sent to a multithreading server which using Health Level Seven protocols records the data in the database. The agents associated to gateway are able to collect, analyse, interpret and store the data in the repository. This gateway is composed by a fault tolerant system that ensures a data store in the database even if the agents are disconnected. The gateway is pervasive, universal, and interoperable and it is able to adapt to any service using streaming data.

A quantitative research about attitudes of pre-service teachers on inclusive education

In this paper we propose to characterize the inclusive philosophy in Thailand as well as to present and discuss results from a quantitative research carried out within the teacher pre-service context, viewed as one of the components that should be addressed by school systems that seek to be inclusive.

Impact of nutritional counseling in reducing serum cholesterol in public health service patients

OBJECTIVE: To assess the impact of nutritional attention on the lipid profile and nutritional status of hypercholesterolemic patients attended in health centers of Belo Horizonte. METHODS: Using nutritional attendance patient record cards from two health units, the evolution of the lipid profile and the nutritional state (BMI) was monitored of 96 hypercholesterolemic patients who received diet. The patients were appraised at the following moments: initial (1st consultation), after 3 months (2nd consultation) and last consultation (variable for each patient). RESULTS: On the first attendance, 44,4% of the patients presented not only high total cholesterol and LDL-c, but also hypertriglyceridemia and 70.3% were overweight or obese, but most patients (75.6%) presented adequate HDL-c levels. There was significant reduction in the BMI, total cholesterol, LDL-c values (p < 0.01) and also in the triglyceride levels (p < 0.05) in the first three months, without alteration in the HDL-c levels. A significant reduction (p < 0.01) was observed in the frequency of individuals with high cholesterol (from 89.6% down to 47.9%), high and very high LDL-c (from 82.6% down to 45.7%), as well as high and very high triglyceride (from 43.6% down to 16.7%). The observed reduction in frequency of the low HDL-c was statistically meaningless. CONCLUSION: This study evidences the effect of the nutritional attention on lipid profile in hypercholesterolemic patients, reinforcing the need for a multiprofessional team to attend them at the public health services.
